Is there any real proof that Nitric Oxide works? A lot of the guys at my gym are telling me they are experiencing focus and more strength from N.O. Explode and Jack3d but still am a little skeptical.
I have tried Jack3d and really it did nothing for me that $4.95 caffine tablet wouldn't do.
So my question is does supplementing Nitric Oxide really work or not?
Thanks
